In a recent year, 22.1% of all registered doctors were female. If there were 51,300 female registered doctors that year, what was the total number of registered doctors? Round your answer to the nearest whole number.

Answer:

$112,710

Step-by-step explanation:

so first we have to find what is 15% of 86700

so 15/100×86700=$13005

so it is written that 86700 is in 2012 means 2010 it will be

2 times more which means 30% that means just have to do is multiply it two times which makes it $26010

so $86700+$26010=$112710

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer with Explanation:

To qualify as a function, each x value may not have more than 1 Y value.

This rules out A, B, and D.

The answer is C.

Why is A incorrect? -5 (the x value) has more than one y value so it is wrong.

Why is B incorrect? 9 (the x value) has more than one y value so it is wrong.

Why is D incorrect? -7 (the x value) has more than one y value so it is wrong.

You can also use the vertical line test to graph these pairs. Then, test by drawing a vertical line through the graph. If the vertical line goes through more than 1 pair, it is not a function.

Answer:

d = 19.8 cm

Step-by-step explanation:

Use the law of cosines

[tex]d^{2} = e^{2} + f^{2} -2ef cos D\\d^{2} = 10^{2} + 14^{2} -2(10)(14) cos 110\\[/tex]

Answer:

2. $76.5

3. $10.12

Step-by-step explanation:

2. 110 × .35 = 38.5

110 - 38.5 = 71.5

71.5 × 1.07 = 76.50

3. 9 × 1.04 = 9.36

9.36 × 1.04 = 9.73

9.73 × 1.04 = 10.12

good luck, i hope this helps :)

2)76.5     110*0.35= 38.5,   110-38.5=71.5*0.07=5.005 or 5,  71.5+5=76.5

3)10.12    y1:9.36, y2:9.73, y3:10.12

4)28 minutes   32*0.08=2.56, 32-2.56=29.44*0.05=1.472, 29.44-11.472=27.968

5)$84   875*0.2=175,    875+175=1050*0.08=84

6)$467.04  562*0.2=112.4, 562-112.4= 449.6*0.06=26.976+449.6=

476.576*0.02=9.53152, 476.576-9.53152=476.04

7)store A, $12.24 a)612*0.3=183.6, 612-183.6=428.4

       b)612*0.2=122.4, 612-122.4=489.6*0.1=48.96 489.60-48.96=440.64

          440.64-428.4=12.24

8)$37.51  tip:32.57*0.18=5.86

   32.57*0.1=3.26,  32.57-3.26=29.31*0.08=2.34, 29.31+2.34+5.86=37.51

9) going of $100 as the price the overall 25% discount to get a final price of $75 would be of a better value, because when you calculate the other 2 options you get the same answer of $76.5.

Step-by-step explanation:

Answer:

Emily's investment = $8,000

Step-by-step explanation:

Let Emily's invested amount = x

Let Samira's amount = y

8% of Emily's amount = 8/100 × x = 0.08x

9% of Samira's amount = 9/100 of y = 0.09y

∴ 0.08x + 0.09y = 1720

multiplying through by 100

8x + 9y = 172000 - - - - - (1)

7% of Emily's amount = 0.07x

6% 0f Samira's amount = 0.06y

0.07x + 0.06x = 1280

multiplying through by 100

7x + 6y = 128000 - - - - - - (2)

Next, let us subtract eqn 2 from eqn 1

equation (1) - equation 2

    8x + 9y = 172000

-

    7x + 6y = 128000

=     x + 3y = 44000 - - - - (3)

from eqn (3) x = 44000 - 3y - - - - - (4)

putting this value of x into eqn 1

8x + 9y = 172000

8 (44000 - 3y) + 9y = 172000

352000 - 24y + 9y = 172000

-15y = 172000 - 352000 = -180000

y = 180000 ÷ 15

y = $12,000

finding x using eqn (4)

x = 44000 - 3y

x = 44000 - 3(12000)

x = 44000 - 36000

x = $8,000

∴ Emily's investment = $8,000

(Multiply both reduced ratio numbers by 3.)

Answer:

42 yd

Step-by-step explanation:

Formula for the area of a rhombus is the length times the width, all divided by 2. A is given as 26, and the total is 546, so the equation is set up like this:

[tex]\frac{26d}{2} =546[/tex]

(Solving for d)

First, multiply both sides by 2 to get:

26d = 1,092

Then, divide both sides by 26 to isolate the variable d:

d = 42

Step-by-step explanation:

Simplifying the expression

5 + 4) 2− 5 × 2

Carl's method

(5 + 4) 2− 5 × 2 -----first error was taking only 4 from the bracket and squaring it.

Instead of solving the bracket as a whole before solving outside. And once she got it wrong from the start, every other solving would be wrong

(5 + 16) − 5 × 2

21 − 5 × 2

16 × 2

32

The right method

In simplifying the expression, we must bring in Mind our Bodmas

Which means we tackle Brackets before division, then multiplication , then addition and lastly subtraction.

(5 + 4) 2− 5 × 2

Solving the bracket first we have

(9)2-5x2

Since there is no division, we move to multiplication and we can see two sites for multiplication(9 x 2 and 5x2)

18-10

Subtracting will give us 8 as our answer.
